Violence in communities may have an additional unseen victim: young peoples’ developing brains.
Experiencing and witnessing violence in their communities can lead to emotional, social and cognitive problems for kids. A new study shows it affects how their developing brains grow, as well.
There are currently no effective treatments for Alzheimer’s disease, which causes may elders to live their last years without recognizing their loved ones, and unable to care for themselves.
Study of the "memory centres" of the brain in adults offers hope for detecting Alzheimer's disease earlier -- before the onset of memory loss.

The scientists behind a controversial new study were surprised by their own results. But they carefully did all they could to 'prove a negative,' and their neurogenesis study is shaking up the field.
Rats were less able to find food after only three days on a diet high in sugar and saturated fat. So could a bad diet also be affect the human brain?
Human memory is complex and neuroscientists are still trying to uncover the mechanisms that lead to memories being formed.
Our memories provide us with insight into events, knowledge of the world around us and influence our actions and behaviours – forming important aspects of our personality.
Our mood is a transient frame of mind that influences how we think and view the world.
Many regions fundamental to mood are buried deep in the most primordial parts of the brain; that is, they are thought to have been among the first brain regions to develop in the human species.
Tiny particles of a mineral known as magnetite may be causing havoc with our health.
Running causes new brain cells to grow. But why does this happen? What is the evolutionary advantage?
Traumatic events can stop the brain storing the context in which they took place.
Brain imaging study shows that we forget the context in which a traumatic event take place which could be crucial to avoiding negative loops.
External enhancements of memory may soon go high-tech.

Could the not-too-distant future hold "brain chip" technologies that we could all use to enhance our memories to the point of perfection? Not so fast: there are big benefits to forgetting.
'Place cells' in the hippocampus are thought to guide us through our space but they may play a part in helping us to imagine future scenarios.
MRIs of 9,000 people have shown that depression shrinks parts of the brain.
Brain damage is caused by persistent depression rather than being a predisposing factor for it, researchers have finally concluded after decades of unconfirmed hypothesising.
A Western diet may be negatively affecting your brain not just your belly.
Do you eat only when you’re actually hungry? Many of us eat even when our bodies don’t need food. Just the thought of food entices us to eat. We think about food when we see other people eating, when we…
Our brain puts us on the map.
If you have taken a walk and would like to return home you need to have an idea of where you are in relation to your destination. To do this, you need to know which way you are facing and also in which…
Run for yourself and your kids.
We all know that exercise is good for our bodies, but current research is revealing that it is also good for our brains. Exercise has been shown to boost executive functions such as planning, working memory…
The hippocampus has been object of scrutiny since the days of Gray’s Anatomy.
This year’s Nobel Prize in medicine recognises work on “cells that constitute a positioning system in the brain.” Those cells are found in the hippocampus. It is just one tiny part of the brain, but this…
Research shows that our memories are not direct representations of past occurrences.
Memory is an essential part of our existence. Who we are, what we know and what we think can all be derived from our ability…
Human brain cells are able to include spatial information in their memories, which enables people to recall experiences that…
A game of bowls now, or Premier League tickets in a month? Your hippocampus can help.
Would you prefer a beer right now or a bottle of champagne next week? So begins an interesting new study published today in the journal PloS Biology. Of course these kinds of choices feature throughout…
Completely immersive virtual reality is still a little way off - unless you have room to move.
Have you ever noticed that even detailed, sophisticated virtual reality experiences don’t feel completely “real”? It all comes down to your inner ear - and a study published earlier this month using rats…
